With the construction of various infrastructures such as transportation and water conservancy, the naturally formed topography and the original geological balance relationship have been changed. If it is not handled properly, the side slope will collapse, and if it is serious, it will lead to debris flow or large-scale landslides. Geological disaster. The existing embankments and slopes are usually reinforced and stabilized by riveting, hanging nets, shotcrete or inlaid with cement blocks (or stones). This method has a good effect on strengthening and stabilizing embankments (slopes).
